Access window object / browser scope from protractor

Assuming you are using a recent version of Protractor, let's say >= 1.1.0, hopefully >= 1.3.1

Attempting to access Browser side JS code directly from Protractor won't work because Protractor runs in NodeJS and every Browser side code is executed through Selenium JsonWireProtocol.

Without further detail, a working example:

browser.get('https://angularjs.org/');

One-liner promise that, as of today, resolves to '1.3.0-rc.3'

browser.executeScript('return window.angular.version.full;');

You can use it directly in an expect statement given Protractor's expect resolves promises for you:

expect(browser.executeScript('return window.angular.version.full;')).  toEqual('1.3.0-rc.3');

Longer example passing a function instead of a string plus without expect resolving the promise for you. i.e. for more control and for doing some fancy thing with the result.

browser.driver.executeScript(function() {    return window.angular.version.full;}).then(function(result) {    console.log('NodeJS-side console log result: ' + result);    //=> NodeJS-side console log result: 1.3.0-rc.3});
